I am choosing between a PLV-60 and a PLC-21N, both by Sanyo. The first is 1366*768 and the second is 1024*768 pixels. However, they both have the same throw ratio. Assuming that I understand correctly that throw ratio is a horizontal measurement, How is it that for a given distance, I will get a smaller picture from having more pixels? Am I missing something? The 16:9 panel at a given throw ratio gives me the same horizontal and less vertical space than the 4:3 panel with fewer pixels. What's wrong with my calculations?

i guess what I'm asking is, forgetting about resolution for a second, the 4:3 projector is going to have the same size 16:9 image as a 16:9 native projector and a larger 4:3 image for any given throw distance if the throw ratios are the same, right?

I'll try to answer this. As I understand it, the throw ratio indeed is the relationship between picture WIDTH and distance from the screen to the projector. So your conclusion is right. For a given throw ratio, a 16:9 native projector image and a 16:9 image from a 4:3 projector will be the same size. The difference is that the 16:9 projector would show 1366 pixels for each line and the 4:3 projector would show 1024 pixels for each line. The 16:9 projector would show 768 lines of pixels, while the 4:3 would show 576 lines of pixels, accounting for the top and bottom black bars. That works out to 1,049,088 pixels for the native display and 589,824 pixels for the 4:3 showing the same size picture. If you added a Panamorph, the 4:3 would use 786,432 pixels. Still not as good as the 16:9, pixel count-wise. If you went with an SXGA projector it would be 1,048,320 pixels (about the same as a 16:9) and 1,397,760 with the Panamorph.
